International Classification:
H01L 21/336
US Classification:
438296, 438938
Abstract:
A semiconductor device having high tensile stress. The semiconductor device comprises a substrate having a source region and a drain region. Each of the source region and the drain region includes a plurality of separated source sections and drain sections, respectively. A shallow trench isolation (STI) region is formed between two separated source sections of the source region and between two separated drain sections of the drain region. A gate stack is formed on the substrate. A tensile inducing layer is formed over the substrate. The tensile inducing layer covers the STI regions, the source region, the drain region, and the gate stack. The tensile inducing layer is an insulation capable of causing tensile stress in the substrate.

International Classification:
H01L 29/76 H01L 29/94
US Classification:
257408, 257336, 438300
Abstract:
Embodiments of the invention provide a transistor with stepped source and drain regions. The stepped regions may provide significant strain in a channel region while minimizing current leakage. The stepped regions may be formed by forming two recesses in a substrate to result in a stepped recess, and forming the source/drain regions in the recesses.

Assignee:
Intel Corporation - Santa Clara CA
International Classification:
H01L 21/84
US Classification:
438300, 438151, 257E21561
Abstract:
A MOS device comprises a gate stack comprising a gate electrode disposed on a gate dielectric, a first spacer and a second spacer formed on laterally opposite sides of the gate stack, a source region proximate to the first spacer, a drain region proximate to the second spacer, and a channel region subjacent to the gate stack and disposed between the source region and the drain region. The MOS device of the invention further includes a buried oxide (BOX) region subjacent to the channel region and disposed between the source region and the drain region. The BOX region enables deeper source and drain regions to be formed to reduce transistor resistance and silicide spike defects while preventing gate edge junction parasitic capacitance.

International Classification:
H01L 21/8238 H01L 31/119
US Classification:
438230, 257311
Abstract:
A method of selectively forming a spacer on a first class of transistors and devices formed by such methods. The method can include depositing a conformal first deposition layer on a substrate with different classes of transistors situated thereon, depositing a blocking layer to at least one class of transistors, dry etching the first deposition layer, removing the blocking layer, depositing a conformal second deposition layer on the substrate, dry etching the second deposition layer and wet etching the remaining first deposition layer. Devices may include transistors of a first class with larger spacers compared to spacers of transistors of a second class.

Giuseppe Curello - Portland OR, US Ian R. Post - Portland OR, US Nick Lindert - Beaverton OR, US Walid M. Hafez - Portland OR, US Chia-Hong Jan - Portland OR, US Mark T. Bohr - Aloha OR, US
A semiconductor device and method to form a semiconductor device is described. The semiconductor includes a gate stack disposed on a substrate. Tip regions are disposed in the substrate on either side of the gate stack. Halo regions are disposed in the substrate adjacent the tip regions. A threshold voltage implant region is disposed in the substrate directly below the gate stack. The concentration of dopant impurity atoms of a particular conductivity type is approximately the same in both the threshold voltage implant region as in the halo regions. The method includes a dopant impurity implant technique having sufficient strength to penetrate a gate stack.
